Fixes two issues: (1) diagrams adding unrequested components (EBS, WAF, Vault,
Monitoring, etc.) by replacing vague "implied dependencies" with a closed
whitelist of 6 technical dependencies and making pre-generation review mandatory
with 3 sections (REQUESTED/TECHNICAL/OPTIONAL). (2) Unstructured data consumption
by adding mandatory Extraction Receipt (CONFIRMED/INFERRED/MISSING), source
tracking in workload profiles, and completeness gate per engagement tier.
